Like tourists at the Leaning Tower of Pisa, hoards of photographers surrounded a scale model of the 220,000-ton, 5,400-passenger Oasis of the Seas, flashbulbs popping from every angle. On one side, the 1:100 model offered a cross-section view of the beast, providing a peek at Central Park, the Boardwalk, the Rising Tide rotating bar, etc. The cost of the model: $200,000. Meanwhile, passersby paid no mind to the lonely ship next to (and dwarfed by) Oasis -- a replica of the 151,400-ton, 2,620-passenger Queen Mary 2, which was the largest and most innovative cruise ship ever built when it debuted in 2003.
